MEDICAL. APPLBANCE.

To all whom it Truly concern: I

Be it known that I, ALBERT O. HEATH, a citizen of'the United States,residin at St. Paul, in the county of Ramsey and tate of Minnesota, haveinventedcertain new and useful Improvements in Medical Appliances, ofwhich the following is a specification,

This invention relates to certain new and useful improvements in medicalap liances, and has reference more particulary to an, improved devicefor the treatment ofhay fever, and other similar ailments. V Theinvention has forits object the production of a simple and inexpensivedevice which can be inserted into the nostrils for the purpose offiltering the air'drawn therein'to in breathing, whereby, injurioussubstances are prevented from coming in contact with and irritating thesensitive membranes of the nose. 1

A further object is to rovide means whereby the filterin materia may bequickly and conveniently c langed as desired.v

A further object is to provide means for facilitating the insertion andremoval of the device intoand'from the nostril, respectively. Theinvention will be hereinafter fully set particularly pointed out in theclaims.

, In the accompanying drawing :Figure 1 is a top plan view of myImproved surgical device. Fig. 2 is a front View thereof. Fig. 3 isaside view. Fig. 4 is a sectional view on line 44, Fig. 1. Fig. -5 is adetail view illustrating the manner of securing the filtering fabric. 3

' Referring to the drawing, 10, 1 I'designate two filtering members eachmade up of an outer ring12, and an inner ring 13, conforming to thecontour of the first ring, with -a sheet of filtering material 14, suchas gauze,

Q grasshnen, chifion, etc. stretched across the open space of the inner.ring and having its edges secured between the:c0ntiguous faces of 0thrings. The. inner rings are connected by a bridge or band 15' the endsof which j are secured to the'inner face of each ring as indicated at16, in such manner as to practically connect the inner adjacent portionsof the filtering members. The rings 12 and 13 are made-0f any suitablematerial, such as cork, hard rubber, German silver, and the like and areshaped to conform to the contour of the nostril 'i. e. they aresubstantially e1 liptical in shape, the contiguous or inner sides,however, being substantially straight,

i In practice after the filtering fabric has been stretched across eachring 13 and the edges thereof confined by catching the same between theouter face of ring 13 and the inner face of ring 12, the device is readyfor use. The bridge or band 1-5 is grasped in such manner as to readilyforce the filtering members'into both nostrils, the bridge-or band 15tering members can be inserted. When it is desired to remove the ,deviceit is only necessary to grasp the bridge or band 15 and the filteringmembers can then be readily withdrawn. The advantages of my improvedsurgical device will be readily apparent.'- It willbe particularly notedthat the same is simple and inexpensive in construction, and when thefiltering fa ric quickly becomes moistened by the secretions of thenose, thereby greatly adding to the .filtering power ofthe device. Itwillbe further observed that the fit the nostril in such manner as to besafely retained thereby and that there are 'no' exposed points orprotuberances that can 1njure filtering fabric in position and foraccomlishing a ready change thereof. It will also lie noted that bfimeans of the bridge or. band the device may ereadily inserted intoposition or removed, as .desired, and that the saine may be readily bentto bring the filter ing memberscloser together or farther apart, asthe-conformation of the patients nose requires. It will be furtherobserved that serving to limit the distance to which said filplaced inposition will thoroughly filter the: air drawn throu h the nostrils.When in use necessary to, prevent foreign particles from personsresiding in localities where sand and I the outer sides being formed ona deeper filtering members are so shaped as to readily the flesh.Another advantage lies' in the simple and efiicientmeans for securingthe while I haveshown and described my improximately'flat and the otherside arranged on a deep curve, whereby said rings conform to theinterior contour of the nostril, the ends of said bridge or'band beingsecured one to each ring-like member and to the inner face of theflattened portion thereof, whereby the ends of said bridge or band willnot lacerate the flesh in placing the rings in the nostril, a

filtering fabric extended across each filter member, and a securing ringfor each filter member conforming to the contour thereof and fittingover the outer face thereof to surround the same and clamp said fabricin position, said rings being formedlofthin bands of smooth metal. r Intestimony whereof-I'have signed-my name to this specification inthepresence of two subscribing itnesses.
